If only I had been honest with myself sooner, I wouldn't have hurt anyone... Aika (older sister) and Risa (younger sister) were childhood friends and we were always together in our school days. I liked Aika, and I was sure she liked me. But we were too close, and nothing ever progressed, and now we're in our thirties. I often visited the share house where the sisters lived together. One day, Aika and I were talking, remembering a story from our school days, and she said, "You're clinging to past glories, so you can't get a girlfriend, even at your age." Why did she have to say something like that... I got angry and retorted, "It's the same for both of us, you don't have a boyfriend! That's the kind of personality you have, so you're single." Risa noticed our argument and comforted me, and when she confessed her feelings to me, we decided to go out... As soon as she heard that we were going out, as a way of getting back at Aika, Aika started seducing me with her breasts without a bra on. I thought my breasts were big, but I didn't know they were this big... My nipples were showing... "Risa, I don't want you to hurt me, so why don't you practice sex with me?" Aika was jealous and desperately tried to get me back, and even though Risa was close by, I was the worst and gave in to Aika's seduction and had sex with her many times. "Do you really love me, Risa?" "I've always loved you, Aika." Why couldn't I say these words sooner? I told Risa my honest feelings. "I thought so... I should have been honest from the beginning." She got angry and left, but she understood, and we finally became lovers...
